SPECIFICATION forming part of Letters Patent No. 233,602, dated October 26, 1880.

Application filed April 21, 1880.

To all whom it may concern:

Be it known that I, OLIVER P. CLAYTON, of Holly Springs, in the county of Cherokee and State of Georgia, have invented certain new and useful Improvements in Blacksmiths Tuyeresz; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in blacksmiths tuyeres; and it consists in a box or air-chamber that is to be connected to the pipe of the bellows, in combination with a vertically-adjustable rod having a grate secured to its top, a vertically-movable stopper to close the opening in the bottom of the airchamber, and a mechanism to partially rotate the grate to crush the clinkers that catch be tween the top of the chamber and the grate, and to raise the stopper to let the ashes out, as will be more fully described hereinafter.

The object of my invention is to provide a means for regulating the draft to the fire from the bellows or other airengine, and from which the cinders and clinkers can be readily removed as soon as they begin to clog up the draft without having to take the tuyere apart in any manner.

Figure 1 is a vertical ,fsection of my invention. Fig. 2 is a side view of the same.

A represents a suitable air-chamber, either of the form here shown or any other that may be preferred, and which is connected, by the pipe B, with the bellows or any other air-engine that may be used. Around the top of this chamberjis secured a flange of any suitable width, by means of which the chamber is supported and secured in position by means of screws or bolts. Upon the top of this flange are secured the two rings or sections O,Which are made removable and are in two different parts, so that in case one of them burns outit can be removed and replaced by another at very small expense. Upon these two sections or rings the firejis' built, and placed just under the hole in the center of the smaller ring is a suitable grate, F, which is secured to the top of the rod H. The edges of this grate are (No model.)

made corrugated, so that when the grate is revolved horizontally it will grind and break the cinders and clinkers which may get in between it and the inner section or ring and thus interfere with the blast. The rod upon which this grate is placed can be adjusted vertically by means of the set-screw l at the bottom, and by this means the opening around the edge of the grate can be made larger or smaller, as may be desired, so as to increase or decrease the force of the blast.

Projecting from one side of the rod H is an arm or lever, J, through which the endwisemoving lever L passes, and which lever has suitable projections N secured to it, so that when the lever is moved back and forth these projections, catching against the arm on alternate sides,will give the grate a rotary motion.

The endwise-movinglever L is supported in position in the bearings O, which have large enough holes made through them to allow the lever to be raised and lowered with the rod H or the arm J may be made with an opening through it sufficiently large to allow the rod H to be moved up and down without affecting the lever at all. When this grate is rotated back and forth the cinders, ashes, and clinkers whiclnare stopping up the draft will be broken and dropped down into the bottom of the chamber A.

In order to prevent the draft from the bellows or air-engine from escaping through the bottom of the chamber, which has a suitable opening through it to discharge the sand and clinker-s, there is placed upon the rod secured to the grate a vertically moving diamondshaped stopper, T, which fits closely around the rod at its upper end, but loosely atits bottom, and which stopper can be raised upward by means of the arm V on the lever L. This lever has not only an endwise motion for revolving the grate, but also a rotary motion. When the lever L has been moved endwise and is revolved, the armVcatches under this stopper and raises it, so as to allow the ashes and cinders which have fallen into the chamber A from the grate to be discharged through the bottom of the air-chamber. This stopper is here shown as being round; but it may be made of any other shape, as its only objectis to close the opening in the bottom of the chamber to prevent the escape of the air, and I when raised to allow the ashes and cinders to fall through.

By means of this invention a tuyere can always be readily cleaned out, so that it will never be necessary to remove any part to get at the obstructions Which may stop up the blast.

By making the rings or sections removable, so that after one or both have been burned out new ones can be pntin, a great savingismade.

Having thus described my invention, I claim- In a tuyere, the combination of air-chamber A, top 0, adjustable rod H, having, a grate, F, at its top, stopper T, and the means de- 1 scribed for rotating the rod back and forth and raising the stopper, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 1st day of April, 1880.
